ELECTRIC WATEB-PURIFIER.

Application filed June 30, 1917.

To all whom it may concern:

Be it known that I, EDWARD M. BARNES, a citizen of. the United States, residing at I Hastings, county of Barry, State of Michigan, have invented certain new and useful Improvements in Electric Water-Purifiers, of which the following is a specification.

vThis invention relates to electric water purifiers.

'Theobjects of this. invention are:

First, to provide an electric water purifier of that type in which spaced electrodes are immersed in the water to be purified, that is simple in structure, economical to manuwhich is deposited thereon during the operation of the device.

Further objects, and objects relating to structural, details, will definitely appear from the detailed description to follow.

I'accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a vertical sectional view through my improved purifier, the electrode holder being shown in side elevation.

Fig. II is a side elevation of my improved electrode holder.

Specification of Letters Patent.

Patented May 21, 1918.

Serial No. 177,956.

Fig. VIII is a plan view of the cover for the water container.

Fig. IX is a plan view of the container with cover removed.

In the drawing, similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the reference character 1 indicates my improved electrode holder as a whole. This holder comprises the cylindrical body member 2 which is provided with a central longitudinal slot 3, the sides of which have the channels or grooves 4 formed therein for receiving the bar electrodes 5. The lower end of the slot 3 is provided with recesses 6 for the lower ends of the electrodes.

A pair of rectangular openings 7 in the upper end of the body member form continuations of the grooves 4 for receiving the upper ends of the electrodes 5 and form between them the spacing block 8 which holds the upper ends of the electrodes in spaced relation. The upper ends of the electrodes are provided with laterally extending lugs 9 which rest upon the upper end of the body member. The upper end of the body member is screw threaded at 10 to receive the cap 12 internally threaded at 11. The cap is provided with a shoulder 13 which ongages the lugs 9 and clamps them onto the upper end of the body member.

' The upper ends of the electrodes are provided-with binding screws 14 for the terminals 15 of the conductors 16. The conductors 16 are supported and protected by a protector of well known design comprising an insulating bushing 17, to which the upper end of the coiled spring 18 is secured. The lower end of the coiled spring is threaded into the upper end of the cap 12.

In the modification disclosed in Fig. VII, instead of providing the electrodes with lugs which project from the edges thereof, the upper ends of the electrodes are bent at right angles thereto, forming the lugs 9 which rest upon the upper end of the body member and are secured thereto by means of thecap 12. The terminals 15 are secure tothe laterally extending lugs 9. 4

The body member and cap may be made of any suitable insulating material, but I preferably make these members ofhard rubber, porcelain, glass, or any other material which can be easily molded. The electrodes are preferably formed of aluminum or aluminum alloy, or graphitic carbon.

The container 20, which is preferably glass, is provided with a faucet 21, suitable gaskets 22 being provided to prevent leaking. The faucet 21 is disposed above the receptacle bottom, so that the purified water may be decanted off from above the precipitated matter in the bottom of the container. The open upper end of the container 20 is provided with a shoulder 23 upon which rests a gasket 24. The cover 25, which may be constructed of glass, porcelain, hard rubber, or any other suitable insulating material, is provided with a flat central boss 26 having an aperture 27 which is larger in diameter than the body member 2. The outer periphery of the cover 25 is provided with a downturned flange 28 which rests upon the gasket 24, and an upwardly projecting annular head or rib 29. Clips 30 engage the rib 29 and the lower side of the shoulder to hold the cover 25 in place.

In use the cylindrical electrode holder is inserted through the aperture 27 with its cap 12 resting upon the boss 26. WVhen current is supplied to the electrodes through the conductors 16-, the matter in suspension in the water will be first coagulated and then precipitated and the water sterilized.

After my purifier has been in use for some time, deposits form upon the surfaces of the electrodes and it becomes necessary, therefore, to remove these deposits. The electrode holder may be freely removed from the container. To make the surface of the electrodes accessible for cleaning, the depth of the groove l is made less than the thickness of the electrodes 5, so that the outer surfaces of the electrodes project beyond the outer surfaces of the walls of the slot 73, as shown in Figs. II and IV. The faces of the electrodes may be quickly cleaned by passing a cloth or a scraping implement through the slot 3. IVhen the outer surfaces 01": the electrodes become worn, the electrodes may be reversed in the grooves 4:. Having thus described my invention, what I claim as new and'desire to secure by Letters Patent, is:
